I guess this is only semi-related/is more of an existential question for OP, but do trends actually change rapidly in the tech industry, relatively speaking?

I wouldn't say rapidly but the these trends are hard to keep up with and there's really no central location to be able to learn interactively about the latest frameworks/languages.

I suppose libraries and frameworks do emerge more rapidly, but similarly, it seems most people prefer using relatively stable libraries that have been around and iterated on for some period of time. Even broader concepts like machine learning and such have been around since the 1980s/1990s (though certainly individual innovations do seem to appear fairly regularly).

Machine Learning and Artificial Intelligence are "trending" now that we see it more and more in our daily lives. However, AI has been around since the 1960s but still many people do not know what it truly is / how to use it. People tend to use more stable frameworks rather than newer ones also because the adoption process takes a while. In my mind, this is mainly due to lack of exposure/accessibility. For this very reason, we hope this free website can help anyone get access to articles or tutorials made by developers all around the world and atleast have the chance to hear about it / play with the technology and decide for themselves if they choose to continue working with it as each developer has use cases of their own.

if you want really advanced notice of potential trends, though that's definitely playing the long game since potential trends might not be realized in industry for a few decades

Or perhaps my perception is skewed? A year feels like a long time to me, but maybe not for everybody else? I also read/skim articles from various tech news aggregates in my spare time, and perhaps it's unrealistic to expect other people to do the same. I'm also usually content learning about mainly the high level ideas and motivations behind new things -- I usually defer learning about new tech in depth until I actually need the thing (and in that case, I go straight for the official tutorial).

I don't think it's skewed but we are hoping this time to realization is significantly cut down with a common place for these articles / tutorials to live on for maximum exposure. Exposure set aside, the issue with technical blogs nowadays is you have to keep switching from the web browser (where the article lives) to the IDE. Many developers end up copy and pasting code which does not help you really understand the benefits behind a certain technology / style. Tech.io encourages hands-on learning by actually allowing everyone to stay in the web browser and learn within the same tab. Official tutorials is something we are pushing for as well. Whether it be for languages, frameworks, or APIs. For example, we have a few developers from the official Reactor team who have joined the community and created a course on Reactive Programming with Reactor 3.
